Application and Market Analysis of Silicon Nitride Ceramics
Silicon Nitride Powder Building
Silicon nitride (Si3N4) is a covalent bond compound composed of silicon as well as nitrogen. It was found in 1857 and also was mass-produced as a ceramic product in 1955. Silicon nitride ceramics have many benefits that metal materials and also polymer materials do not have, such as high temperature resistance (bending toughness over 350MPa at 1200 ℃), acid and alkali corrosion resistance, self-lubrication and so forth. Silicon nitride ceramics are commonly used in aerospace, national defense and mechanical areas.
Prep Work Method of Silicon Nitride Ceramics
The preparation of silicon nitride ceramic material first needs to acquire silicon nitride powder, and then via molding, sintering and also other processes, the needed silicon nitride ceramic is ultimately gotten. the main preparation approaches of the powder include silicon powder nitriding approach, liquid phase response approach and also self-propagating heat synthesis technique.
The main developing processes of silicon nitride ceramics are dry pushing, cool isostatic pushing and tape spreading, and also the main sintering processes are warm pressing sintering, air pressure sintering, warm isostatic pressing sintering, stimulate plasma sintering and more.
Silicon Nitride Ceramics Application in Mechanical Industry
Silicon nitride ceramics are primarily made use of as shutoffs, pipes, grading wheels and also ceramic devices in the mechanical market, and also one of the most widely utilized is silicon nitride ceramic bearing spheres.
The rate of silicon nitride bearing ball is as high as 600000 changes per minute in use, which is primarily made use of in accuracy equipment device pin, motorized pin high-speed bearings, aerospace engines, automotive engine bearings and also other devices bearings.
Compared to steel round, silicon nitride ceramic bearing sphere has outstanding advantages: low thickness, heat resistance, self-lubrication and also rust resistance. As a high-speed revolving body, the ceramic sphere produces centrifugal anxiety, and also the reduced thickness of silicon nitride decreases the centrifugal tension on the high-speed turning outer ring.
Dense Si3N4 porcelains likewise display high crack toughness, high modulus and also self-lubricity, which can resist a selection of wear and also withstand harsh environments that might result in cracks, contortion or collapse of various other ceramic materials, including severe temperature level, large temperature level difference and also ultra-high vacuum. Silicon nitride bearings are expected to be commonly used in numerous markets.
Silicon Nitride Market Analysis
The production of high-end silicon nitride ceramic items is still controlled by Japanese, European and American enterprises. The international market share and the leading pressure of advancement instructions are still controlled by popular foreign enterprises. Japanese Kyocera, Toshibx Seridan, CoorsTek as well as British Sailon are the most representative.
According to the global market research firm MARKETSANDMARKETS, the global market dimension of silicon nitride will expand at a compound yearly development rate of 5.8% during the analysis duration (2020-2027). From $1.4 million in 2020, it is anticipated to get to $149 million by 2027.
